UPJ1A181MED

The UPJ1A181MED is a radial-lead aluminum electrolytic capacitor from Nichicon's UPJ series, offering 180 µF capacitance at a 10 V rating with polarized construction. Engineered for general-purpose power filtering and decoupling, it provides measurable ripple-handling and low-loss performance in a compact φ6.3 × 11 mm can.

Key value propositions include predictable ripple-current capability across low and high frequencies, a wide operating temperature range from −55°C to 105°C, and RoHS compliance—attributes that support reliable power-supply smoothing and local energy storage in compact assemblies.

Key Features

• Electrical Capacity: 180 µF nominal capacitance with ±20% tolerance, suited for bulk decoupling and power-rail smoothing.
• Rated Voltage & Polarization: 10 V rated voltage; polarized design for DC applications.
• Low-loss Characteristic: Tangent of loss angle (tan δ) of 0.19 at the rated voltage, supporting lower dissipation in circuit operation.
• Ripple Current Capability: Specified ripple currents of 110.7 mA at 120 Hz (low frequency) and 205 mA at 200 kHz (high frequency), useful for both line-frequency and switching-frequency filtering.
• Leakage Current: Leakage current specified at 54 µA, providing predictable standby behavior after voltage application.
• Reliability & Lifetime: 2000 hours life at 105°C rating for endurance under elevated operating temperatures.
• Package & Mounting: Radial, can-style package (φ6.3 × 11 mm) with 2.5 mm lead spacing; supplied bulk/no terminal forming for through-hole assembly workflows.
• Operating Range & Compliance: Operating temperature −55°C to 105°C; RoHS compliant.
• Product Status: End of Life.

Typical Applications

• Switching Power Supplies: Local output smoothing and ripple suppression where low-loss behavior and measurable high-frequency ripple capability are required.
• DC-DC Converter Filtering: Input/output decoupling for compact converters, leveraging the component's radial can package and specified ripple ratings.
• General-Purpose Power Rails: Bulk decoupling on consumer and industrial PCBs where a 10 V polarized capacitor of compact size is needed.

Unique Advantages

• Compact radial can: φ6.3 × 11 mm package provides high capacitance in a small footprint for dense board layouts.
• Quantified ripple performance: Dual ripple-current specifications at 120 Hz and 200 kHz let designers size capacitance for both low- and high-frequency noise sources.
• Predictable leakage and loss: 54 µA leakage and 0.19 tan δ at rated voltage give clear metrics for energy loss and standby current budgeting.
• Wide temperature range: −55°C to 105°C operating range supports use across a broad set of environmental conditions.
• Through-hole assembly friendly: Radial leads with 2.5 mm spacing and bulk/no terminal forming supply support manual or wave-through-hole processes.
